[OS X TeX] Texmaker vs. TexShop

[Richard Seguin]

I’m not sure why overheating would be a TeXShop issue. The intensive processing takes place during typesetting. Does TexLive make use of the graphics processor for computations? For example, photo editing software makes use of  GPUs for things like vector and other such computations for which GPUs are optimized.

In a previous post I did note that PDFKit, which TeXShop uses, seems to have something like a memory leak problem:

They claimed that Skim had the same problem. They didn’t mention TeXShop, but I assumed that it would have the same problem if the other two did. I’m running El Capitan myself, so I checked it out.

As I paged through the document one page at a time, the RAM usage kept increasing with each page, and when I hit the end, Skim was consuming an astounding 726MB. It did drop back down to 50MB when I closed the document, so it isn’t clear to me if this is actually technically a memory leak problem, or that this is a massive memory hog problem.

The fact is MacBook Pros early and late 2011 have a problem, Apple issued a recall, I saw last month, just go there (Apple Store) and replace it. Majority of MacBook pros of this era had this issue of burning  the logic board due to overheat of GPU, was a fault in AMD chipsets at the time, also it seems to have something or burn too the battery temp sensor.

Apple does not design laptops for optimal heat dissipation (form over function!), and, in some cases, there have also been problems with the heatsink adhesive that attaches the heatsink to the processor. In my case, I believe that it was the photo editing software Aperture that put enough stress on the graphics card to cause it to fail. My logic board was replaced for free under the result of a class action lawsuit.
